Connected dominating set based network coding for SDN

In order to address complex and resource demanding applications. Software Defined Networks (SDN) and Network Coding (NC) paradigm has garnered much attention in recent years. NC is the key concept of networking to enhance network throughput and reliability, whereas SDN is the modern network architecture to virtualized network services for making route more flexible and allocating network resources on-the-fly. NC advances the conventional store-and-forward concept of packet flow by the notion of a store-code-forward among the intermediate nodes. With effect, source and destination no longer need to track singular packets, but rather targeting enough autonomous encoded packets. The practical coding gain lies on the complication of deploying coding techniques over the classical network of routers. The comprehensive view of SDN can overcome this challenge by separating network architecture into control plane and data plane. This paper counsels the use of SDN which not only assist traffic, but also manage buffering, scheduling and processing of packets. Further, the paper presents NC functionality rich Connected Dominated Set based Flow-oriented Coding-aware Routing technique (CFCR) to optimize number of transmissions over the SDN network.
